Needs to be spray foam. When dry that stuff is pretty damn hard. Also would allow for quick facing to make it flat and easy to drill into to run plumbing and electrical through. Print and then anchor it. Or print and move it then anchor it. Also guessing it would be like having a lot of insulation.

Is adding drywall to concrete not a pita?

The idea is cool, I just don’t think it’ll ever take off unless we can come up with some kind of better material than concrete. Needs to be a dual head printer that fuses outer concrete with inner softer shit that’s not radioactive, can easily drill into for running wires and plumbing, hanging pictures, etc.

Also, are there no Radon concerns? I have a Radon vent and only my basement is concrete. Living inside a radioactive cube seems unhealthy.

If it ends up being significantly cheaper than current construction to produce, the stuff we are talking about can all be resolved. If it isn't significantly cheaper, than its nothing more than a "cool idea". It is definitely faster, which is important, but its gotta be cheaper.

Im questioning how much faster it really is.

In the demo video (which I only skimmed because fuck videos) it looked like they built a small structure without any of the finishing work. No plumbing, no electrical, no hardware.

To just frame and side a structure that size? I bet you can hire one competent contractor and a team of Mexicans and get it done with standard methods in similar time. And be left with a structure that would be a whole lot easier to finish.

The original article said they built the house of 5 days (printer running 24/7). They dont specific but I assumed that was the structure itself and then it still needed the piping and finishing etc.

That seems slower than current build times. Watching a new housing addition go up behind us. They pour the basement in a few hours. Prefab frame arrives the next week and it is fully framed and has a roof on day two. Idk how much time it takes to fab the frame and load it but I’d liken that to bringing the printer and assembling it, etc.

When they were building our next door neighbors I watched one guy with a small crane do the entire first floor beams by himself in a day. Next day the entire crew showed up and they had the roof on day one, guessing because of that dudes prework the previous day. These are 2 story, full basement 3k+ sq foot homes too, compared to those one story small printed houses.

I know the 3D printing can only get faster and cheaper but it doesn’t seem close yet. Like mentioned earlier, we don’t really know the true cost yet because it’s so early and specialized still.

Yeah it's hard to really discuss the viability of the approach without knowing how extensible certain aspects are. Are there any significant impediments to dramatically increasing the print speed, or having people place plumbing electrical in as its being laid down? Can the mechatronic gantry being used to print it be reduced to something that doesn't require a flat landscape? ex a cement truck boom? Is the tensile strength of the materials used enough to be used in a variety of ways? If these things are answered in a positive way it could be great in the future.

Yeah, seems like it took them 5 days to "frame" it w concrete. And technically took them "weeks" just 5 "working days".

That's a long ass time. And I bet it's probably still twice as expensive, even considering redonkulous lumber costs.

They have all of Mericas SAPs, Data, Tech. Just cause they make shitty stuff and sell it to everyone doesn't mean they aren't employing top notch shit in their RnD department and making huge scientific advances. What, you think China is only in the top 3 in the world because they eat bats?

Their shitty stuff includes fake data. They make a lot of that.

Its rule #1 when it comes to Chinese Science: if all the research was done in China, and all the people on the paper are Chinese, its fake.

I mean, this stuff is like Nigerian prince emails. It feels a little silly even having to say out lout that its fake.

I mean, they are still the only country in the world that has multiple papers every year showing that acupuncture "works" (every study done in other countries has concluded it to be undistinguishable from placebo).

Researchers create quantum microscope that can see the impossible

In a major scientific leap, University of Queensland researchers have created a quantum microscope that can reveal biological structures that would otherwise be impossible to see.

This microscope has the potential to be huge in terms of advancements. A lot of things we know are basically inferred and even biology paper reproduction rates are pretty dog shit right now so this has the potential to clear up tons of misconceptions/bad papers out there. I'd be curious if it's good enough to see mRNA protein folding.. that shit right there is the holy grail of biotechnology. A clear predictable understanding of mRNA and protein folding turns DNA modifications into the equivalent of computer programming biology.
